Winter tends to be cold, dark, and monochromatic. But in the world's polar regions winter can be surprisingly colorful, thanks to icebergs formed with blues, greens, blacks, and browns--usually in the form of stripes. These stripes were caused when layers of sediment, ice, or other materials were picked up or seeped into cracks as a glacier formed over the millennia. Be it a black layer of soot from an ancient volcanic event, or water that flash froze in place, each layer tells a story and..

There's one major issue with getting an up close view of collapsing icebergs crashing into the sea off the coast of Greenland, and that's keeping your pants dry when the angry wall of water that forms comes rushing toward you at high speeds. Jens Moller learned that lesson the hard way last week. Moller held his camera steady on the iceberg after hearing it crack. The 23-year-old mechanical engineer was on board his uncle's boat with an Australian tourist. Luckily, Moller's..

A NASA scientist and her colleagues were able to observe for the first time the power of an earthquake and tsunami to break off large icebergs a hemisphere away.Kelly Brunt, a cryosphere specialist at Goddard Space Flight Center, Greenbelt, Md., and colleagues were able to link the calving of icebergs from the Sulzberger Ice Shelf in Antarctica following the Tohoku Tsunami, which originated with an earthquake off the coast of Japan in March 2011. The finding, detailed in a paper..
